Abstract

In a fluid operated tool of the type having firing control means comprising two separate and independent triggering means shiftable independently and in any order between normal and firing positions and requiring both triggering means to be concurrently in their firing positions to actuate the tool, safety means introducing into the firing sequence of the firing control means a time limit within which both triggering means must achieve their firing positions. If both triggering means do not achieve their firing positions within the time limit, the firing sequence must be reinitiated with a selected one or both of the triggering means initially in their normal positions.
